Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies fail to adapt effectively to signal coverage enhancement scenarios, leading to inefficient use of resources and energy consumption in small data transmission (SDT) for terminals with and without coverage enhancement (CE) capabilities.
Innovation Solution
Determine separate threshold values for signal transmission quality based on configuration information for terminals with and without CE capabilities to optimize small data transmission (SDT) in networks supporting CE, allowing terminals with CE to perform SDT under lower quality conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same threshold value is configured for both terminals supporting CE and terminals not supporting CE, then the configuration is simple, but terminals supporting CE cannot perform SDT under lower signal transmission quality conditions
Solution Approach 1:
The patent segments the threshold configuration into two separate threshold values: one for terminals supporting CE and another for terminals not supporting CE. This segmentation allows each terminal type to have optimized thresholds suited to their capabilities, enabling terminals supporting CE to perform SDT under lower signal transmission quality conditions while maintaining simple configuration overall.
Solution Approach 2:
The patent applies local quality by providing different threshold values tailored to specific terminal types. Terminals supporting CE receive a threshold configuration that reflects their enhanced capability to handle lower signal quality, while terminals without CE receive appropriate thresholds for their capabilities. This localized optimization improves overall system adaptability without requiring complex global reconfiguration.
2Adaptability or versatility
If separate threshold values are configured for terminals supporting CE and terminals not supporting CE, then adaptability is improved, but configuration complexity increases
Solution Approach 1:
The patent implements dynamic threshold configuration where the appropriate threshold value is selected based on the terminal's CE capability. The system dynamically adapts the threshold setting according to the terminal type, allowing terminals supporting CE to use lower thresholds for SDT while terminals without CE use higher thresholds, thereby improving adaptability without requiring manual complex configuration management.
3Loss of energy
If a higher threshold value is used for SDT, then resource waste is reduced, but terminals supporting CE cannot transmit data under lower signal quality conditions
Solution Approach 1:
The patent changes the threshold parameter based on terminal capability. Terminals supporting CE are assigned a lower threshold value that allows them to perform SDT under lower signal transmission quality conditions, reducing energy consumption and resource waste in coverage enhancement scenarios. Terminals without CE maintain appropriate higher thresholds to prevent resource waste, thus balancing energy efficiency with reliable data transmission for each terminal type.
